Abstract: Mitochondria are subcellular organelles with the most well-known and best-characterized function of adenosine triphosphate (ATP) production through oxidative phosphorylation (OXPHOS). Mitochondria play an important role in apoptosis, a fundamental biological process by which cells die in a programmed manner and are the strategic point in the cell death cascade. Alterations in respiratory activity and mitochondrial DNA (mtDNA) abnormalities appear to be a general feature of malignant cells. The presence of mtDNA mutations has been reported in most types of cancer. However, the functional consequences and clinical relevance of these mutations are not clear.
